The object of the present invention is to obtain a low profile electrolytic copper foil with a low surface roughness at the rough surface side in the electrolytic copper foil manufacture using a cathode drum and, particularly, to obtain an electrolytic copper foil with excellent elongation and tensile strength that permits fine patterning. At least one of the focal region and the sample is adjusted through a plurality of adjustment stages within an adjustment range so as to vary a location of the focal region relative to the surface. Next, for a given user the system obtains an identity certificate from a certificate authority. The modulation control information and the demodulation control information may be received via a communication device comprising said chip. More specifically, the invention demonstrates that intranasal administration of ketamine is effective to ameliorate the symptoms of depression in a patient who has not responded to an adequate trial of one antidepressant in the current episode and has recurrent or chronic depressive symptoms. The slide is connected to the door by a mechanical transmission in such a way that a movement of advance of the slide causes a simultaneous movement of opening of the door, and a movement of backing off of the slide causes a simultaneous movement of closing of the door.
